He noticed through a bedroom window (without curtains) a white mail and an Aboriginal female, both naked, going through the motions of sexual intercourse.
He was a bit annoyed and reported the couple to his police colleagues
s 47 Summary Offences Act (1987) (NT) : A person who is guilty of an offensive behaviour 'in or within the view of any person in any ... public place' is guilty of an offence.
s 31 criminal code (NT): Excuses a person form criminal responsibility for an 'act, omission or event unless it was intended or foreseen by him as a possible consequence of his conduct'
s 23 Criminal Code (NT): A person will not be guilty of an offence if 'any act or omission or event constituting that offence was done, made, caused by him, was authorized, justified or excused
s 26 Criminal code (NT): An act or omission is 'authorized' if it was done in the exercise of a right granted or recognized by law.
considering the decision of Brennan J in Hey Kaw Teh's case, mens rea is an essential element in every statutory offence and 'offensive behaviour' unless, having regard to the language and subject matter, mens rea is excluded either expressly or by necessary implication
there is a presumption that statute does not impose criminal liability without mens rea
he believes if an ordinary person was asked whether it would be just to convict and punish for offensive behaviour someone who was unaware that his conduct could be seen by a person in a public place, the answer would unhesitatingly be in the negative
the essence of 'offensive behaviour' is the offending of another person and such offending must be intended
Since the act of offending a person is integral to the proscribed conduct of 'offensive behaviour', then by virtue of s 31 Criminal Code (NT), the offender is excluded from criminal liability unless offending was intended or foreseen by him as a possible consequence of his conduct
